Description

 Description - Use of a method of increasing the height of the back groove and/or widening the righting head and implementing the method to increase and/or widen the righting head of the back groove

Technical field

 The invention belongs to the field of machinery, and is particularly suitable for a method for increasing and/or widening a righting impact head in a field of mining or engineering machinery, and implementing the method for increasing the height of the back groove and/or widening the righting head Device.

 Shearers, roadheaders, excavators are collectively referred to as mining machines, reciprocating impact mining machines, and reciprocating impact excavators. In order to quickly and efficiently extract rock or coal seams or cement concrete or siltstone, etc., in the upper and lower parts of the impact guide The guide rolling elements are all provided, because the upper and lower rolling bodies need to occupy a large space, so the size of the impact guiding member supporting the righting impact head is relatively reduced, resulting in insufficient strength of the supporting and supporting impact head, so that the impact power box drives the impact tooth to impact the material up and down. The tooth has a large torque, and the uneven force is easy to cause the impact head to generate a lateral force, and the upper and lower guiding rolling elements are disposed on the outer side of the impact guiding member to increase the height and/or the width of the impact guiding mechanism, and the multi-layer impact is set. The higher guiding mechanism of the head must make the upper and lower impact heads higher and larger, and the higher impact head must increase the impact resistance, especially because the impact head such as the shearer must be larger than the height and width of the power box. If the impact head impacts more than the height and width of the power box and the total height of the mining is greater than the total height of the fuselage, The power box and the fuselage pass through to achieve continuous coal mining. At the same time, the reciprocating impact mining machine must increase the impact head in order to match other equipment. For example, the reciprocating impact shearer must have a certain amount of mining undercover in order to match the flexible scraper conveyor for reloading. In order to facilitate the smooth advancement of the hydraulic support, there must be sufficient cutting amount. Therefore, the impact head must be set. There is a certain height, that is, the impact head must be made larger and heavier, but the larger and heavier impact head impacts the material when the material contact area is large, so that the reaction force is concentrated and powerful, and the impact reaction force is transmitted to the guiding mechanism. After the driving mechanism and the fuselage, the guiding mechanism and the driving mechanism are easily damaged, so that the impact power box and the like are damaged prematurely, and the impact reaction force and the fuselage are formed to resonate to deform the body, and in severe cases, the impact region collapses, etc., causing problems. The device is not capable of continuous loss of continuous operation. In order to solve the above problems, the present invention proposes a method for increasing and/or widening the righting impact head for the back groove and for increasing and/or widening the back groove by implementing the method.

The anti-discrimination mechanism is arranged at the connection between the driving mechanism and the impact head, and the anti-discrimination mechanism effectively prevents damage of the connecting rod and the impact driving mechanism by the impact reaction force, and buffers the impact vibration of the impact box.

 19. Rolling friction on the back groove structure greatly enhances the anti-distraction force of each tooth holder, and its anti-screening strength is increased by more than 2 times, and the flexibility of combining different heights of mining machines is greatly improved. Rolling friction to back groove structure The volume and height of a single impact head are greatly reduced, so that the impact head is suitable for mining materials of different heights. By reducing the impact resistance and increasing the impact strength, the mining machine can extract the functions of materials of different hardness and different materials, and break through the mining machine.
